Rubber composition for coating metal cord, steel cord-rubber composite, tire, and chemical product

A rubber composition for coating a metal cord, comprising

• a rubber component,
• carbon black having an adsorption specific surface area of cetyltrimethylammonium bromide (CTAB) of 110 m2/g to 160 m2/g, a half width ΔD50 of a peak including a Stokes equivalent diameter Dst that is the most frequent in an aggregate distribution obtained with a centrifugal sedimentation method of 60 nm or less, and a ratio of the ΔD50 to the Dst, which is expressed as ΔD50/Dst, of 0.95 or less,
• silica having a CTAB adsorption specific surface area of 200 m2/g or more, and
• a vulcanizing agent, wherein
• a content of the carbon black is larger than a content of the silica, and a content of the vulcanizing agent is 3.0 parts by mass to 7.0 parts by mass with respect to 100 parts by mass of the rubber component.
